Abstract
The invention relates to an anti-collision structure of the car door. The invention has an additional anti-collision bolt structure based on the traditional car door structure. Bolt gears with a welding nut on the internal plate of the car door to connect with the car door. A matching hole is arranged on the corresponding position of side wall. When collision happens, the anti-collision bolt will balance out the bore brink on the side wall. According to structural mechanics principle, the structure can compensate for the deficiency of an anti-collision plate or an anti-collision rod during the collision, thus effectively improving the anti-collision ability of the car door. In addition, impact energy can be led to the bottom of the car door and to the side wall to possibly reduce the deformation of the door, thus keeping the integrity of the car body and giving maximum possible protection to an occupant to prevent an occupant from getting hurt.
Description
Technical field
The present invention relates to a kind of automotive body structure, be specifically related to a kind of anticollision structure of vehicle door.
Background technology
Along with the continuous development of China's automobile industry, the crashworthiness of automobile is more and more paid attention to by the customer.As everyone knows, automobile will serious threat arrive driver and passenger's life security so if the distortion of automobile door structure is excessive, open difficulty in head-on crash, offset collision and side collision process.
Especially for liter-car, the body structure design must be satisfied the same collision laws and regulations requirement of big discharge capacity automobile in limited space, design must be considered when car door is subjected to clashing into for body structure, alleviate the deformation extent of door by some structure Design, thereby can reduce the injury of automobile impacting the passenger.This technology also is in the invention stage at present.
In order to slow down the distortion of automobile door structure in the collision process, traditional solution is at present, increases Crashworthy plate or crash-proof pole structure on door, improves the anti-impact strength and the rigidity of door with this, increases the buffer capacity of car door.But crash bar itself exists some defectives with the Crashworthy plate structure: crash bar is connected with inner plate of car door at its assembly, and strength and stiffness partly are often very difficult to be mated, in automobile collision procedure, be easy to cause connector gross distortion or inefficacy, thereby the dispersion and the conduction of influence collision back strength, the safety that threatens driver and passenger; And if the not science of the opening section of Crashworthy plate design, the strength and stiffness of total will be subjected to very big influence so, are difficult to the crashproof requirement that reaches desirable.
Summary of the invention
The present invention is the concrete application of structural mechanics principle on vehicle body structure; consider the theory that collision back strength is disperseed; designed the special construction of this crashproof bolt; it has strengthened the crashproof ability of car door; and collision energy importing car door bottom; reduce the distortion of door as far as possible, keep the integrality of vehicle body, thereby protect the occupant to preserve to greatest extent.
Problem to be solved by this invention is: automobile in head-on crash, offset collision and side collision process, thereby cause car door distortion easily, open the dispersion and the conduction of difficulty influence collision back strength, serious threat driver and passenger's life security.
Technical scheme of the present invention is summarised as and adds a crashproof bolt arrangement in the traditional vehicle door structure, in order to strengthening car door intensity, so that the crashproof resistance of car door when improving bump, reduce the distortion of door as far as possible, reduce the intrusion amount, strengthen safety guarantee.Thereby the protection occupant preserves from; thereby this bolt by with inner plate of car door on welded nut match and be connected with arrangements for automotive doors; and the corresponding with it position of gusset has sizeable hole; when automobile when bumping; crashproof bolt just can offset with the bore edges on the gusset; according to the structural mechanics principle; this structure can remedy the deficiency of Crashworthy plate or crash bar in striking process; effectively strengthen the crashproof ability of car door; and collision energy importing car door bottom and gusset part; reduce the distortion of door as far as possible, keep the integrality of vehicle body, thereby protect the occupant to preserve to greatest extent.
Concrete technical scheme is as follows:
A kind of anticollision structure of vehicle door, comprise crashproof bolt, welded nut, inner plate of car door and side-wall outer-plate, wherein inner plate of car door is provided with welded nut, thereby crashproof bolt cooperates with welded nut and is connected with inner plate of car door, and the correspondence position of side-wall outer-plate and bolt has the hole, and an end of crashproof bolt stretches in this hole.
Wherein can add the car door stiffener on the inner plate of car door, thereby crashproof bolt is connected with this car door stiffener by cooperating with welded nut.
Can add the gusset stiffener on the side-wall outer-plate, also be provided with the hole on this gusset stiffener, the described end that crashproof bolt stretches into side-wall outer-plate stretches in this hole.
The aperture in described hole can be identical with the external diameter of crashproof bolt, and promptly crashproof bolt contacts with described hole; The aperture in described hole also can be greater than the external diameter of crashproof bolt, and according to the collision expection suitable big small-bore is set.
The present invention has collided cardinal principle having understood---aspect the transmission of power, by designing a kind of new structure, the strength that collision is produced imports car door bottom and gusset part, and the advantage of doing like this is exactly to reduce the distortion of door as far as possible, guarantees occupant's living space to greatest extent.
Compared with prior art, this structure can be in head-on crash, offset collision or the side collision of automotive front, have good longitudinal rigidity and bending rigidity, strengthen the impact strength of door panel, have good loading transfer path, stressed even, when side collision, have good bending resistance, can reduce the distortion of car door, can also strengthen the static anti-pressure ability of car door; Simultaneously, also have simple in structure, be convenient to characteristics such as replacing, low cost of manufacture, long service life.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done the explanation in a nearly step:
Automobile collision preventing bolt (5) by with inner plate of car door (6) on welded nut (4) thereby match be connected with automotive door assembly, and have sizeable hole on side-wall outer-plate (2) and the gusset stiffener (1), when automobile when bumping, crashproof bolt just can offset with the bore edges on the gusset, according to the structural mechanics principle, this structure can remedy the deficiency of Crashworthy plate or crash bar in striking process, effectively strengthen the crashproof ability of car door, and collision energy importing car door bottom and gusset part, reduce the distortion of door as far as possible, keep the integrality of vehicle body, thereby guarantee that to greatest extent the occupant preserves from.
